What Genetic Screening Looks For
NxGen has a comprehensive set of genetic screens — both single screens or sets of screens known as "panels." We offer two basic types of screens: carrier screens (which everyone can benefit from) and preimplantation screens (which are for couples pursuing in vitro fertilization). Everyone carries genetic conditions within their DNA. NxGen MDx screens for the most common genetic conditions within any population to determine if you carry one of these and ultimately, to uncover your risk for passing it to your children.
Discovering Your Genetic Inheritance
The human body is made of trillions of cells. The vast majority of our cells contain our genetic information, which is inherited from our parents in the form of DNA (deoxyribonucleic acid). A gene is a segment of DNA that is responsible for providing instructions, or a recipe, for how to make a specific protein that the human body needs for normal growth and development. If there are changes (or mutations) in the recipe of a gene, that protein will be affected in some way and may not be able to complete its job in the human body. Genes are located on larger structures called chromosomes. Humans typically have 23 pairs of chromosomes, which we inherit from our parents—giving us two different copies of each gene that we have. Generally, genes can be either "recessive" or "dominant." The charts below show the how genes can be inherited and cause disease based on whether they are recessive or dominant.
Recessive Genetic Disease
In order for carriers to pass on a recessive gene, both partners would have to be carriers of the same genetic disease.
Dominant Genetic Disease
